Description

Technical Field

[0001] The utility model relates to the technical field of online weighing of health food, in particular to an online weighing auxiliary structure for health food packaging. Background Art

[0002] In order to facilitate consumers to take health food with Chinese medicine as the main component, most of the existing health food with Chinese medicine as the main component choose to directly make the health food into granules or powders, and quantitatively pack them into health food packaging bags through, for example, powder packaging machines. This avoids the inconvenience of long-term decoction of traditional Chinese medicine, and is convenient for consumers to take it directly with boiled water according to the instructions of the health food.

[0003] Since health food also involves the dosage of some Chinese medicine, the weight of the Chinese medicine granules in the packaging bag must meet the prescribed standards before it can be put on the market. The current conventional production method is to directly set a belt weighing scale at one end of the discharge port of the powder packaging machine. The existing belt weighing scale can complete the weight detection of the health food packaging bag while conveying the health food packaging bag containing Chinese medicine granules. For example, the Chinese patent "A swing arm rejector for dynamic checkweigher" with the authorization announcement number CN208513088U discloses a swing arm rejecting mechanism on the belt weighing scale, which can promptly reject the unqualified health food packaging bags to prevent unqualified products from flowing into the next process.

[0004] The applicant found that a large number of health food packaging bags were rejected by the rejection mechanism during the use of the existing belt weighing scale, and after weight testing of these rejected health food packaging bags, it was found that the weight of some of them was qualified. After long-term observation and testing, the applicant found that when the health food packaging bag is located in the middle position of the belt width direction on the belt weighing scale, the weighing result is most accurate; when the health food packaging bag is located at the edge of the belt, the weighing result will have a large error, which will trigger the rejection mechanism to reject the health food packaging bags that are mistakenly considered to be unqualified products, resulting in waste. Therefore, how to ensure that the health food packaging bag can be accurately located in the middle of the belt is an important measure to reduce the unqualified rate in the production process and avoid the waste of health food. Utility Model Content

[0005] In view of the problem existing in the prior art: when the health food packaging bag is located at the edge of the belt, a large error will appear in the weighing result, resulting in the health food packaging bag being rejected, causing huge waste. The purpose of the utility model is to provide an online weighing auxiliary structure for health food packaging. By setting a connecting auxiliary structure between the upstream powder packaging machine and the downstream belt weighing scale, the health food packaging bag falling from the discharge port of the powder packaging machine can accurately fall into the middle position of the belt weighing scale, avoiding the triggering of the rejection mechanism of the belt weighing scale due to the error of the weighing result, thereby achieving the invention purpose of reducing the unqualified rate and avoiding the waste of health food.

[0006] In order to achieve the above object, the technical solution of the utility model is:

[0007] A health food packaging online weighing auxiliary structure is located between a powder packaging machine and a belt weighing scale. The auxiliary structure includes a guide support assembly and a blowing assembly. The guide support assembly is installed and fixed below the discharge port of the powder packaging machine. The guide support assembly includes a guide plate. The guide plate extends obliquely downward to just above the belt of the belt weighing scale. The blowing assembly includes a support rod and an air nozzle. The air nozzle is fixed above the guide plate through the support rod. The air nozzle is aligned with the guide plate and blows air toward the guide plate.

[0008] The utility model is further configured as follows: the guide plate comprises a first guide plate and a second guide plate, and the inclination degree of the first guide plate is greater than the inclination degree of the second guide plate.

[0009] The utility model is further configured as follows: the guide support assembly also includes a third guide plate and a limit plate, the two ends of the third guide plate are respectively connected to the first guide plate and the second guide plate, and the two ends of the first guide plate, the second guide plate and the third guide plate in the width direction are each provided with a limit plate, and the width of the second guide plate is smaller than the width of the first guide plate.

[0010] The utility model is further configured as follows: the angle between the first guide plate and the horizontal direction is 45 degrees, and the angle between the second guide plate and the horizontal direction is 30 degrees.

[0011] The utility model is further configured such that the angle between the blowing direction of the air nozzle and the first guide plate is in the range of 30-60 degrees.

[0012] The utility model is further configured as follows: the angle between the blowing direction of the air nozzle and the first guide plate is 45 degrees.

[0013] The utility model is further configured as follows: the auxiliary structure also includes a flexible transition piece, and the flexible transition piece is installed and fixed on one end of the second guide plate close to the belt.

[0014] The utility model is further configured as follows: one end of the flexible transition piece is fixed to the bottom of the second guide plate, and the other end of the flexible transition piece is suspended and arranged just above the belt.

[0015] The utility model is further configured as follows: the flexible transition piece is composed of a plurality of flexible soft rods arranged in an arranged manner.

[0016] The utility model is further configured as follows: the flexible soft rod is made of silicone material.

[0017] In summary, the beneficial effects achieved by the present invention are as follows:

[0018] (1) The auxiliary structure in the utility model is installed below the discharge port of the powder packaging machine, and uses a guide plate to guide the health food packaging bag dropped from the discharge port to slowly slide along the guide plate to the top of the belt. In the process, the air nozzle in the blowing assembly can also blow air toward the health food packaging bag dropped onto the guide plate, which not only prevents the health food packaging bag from rolling and shaking after the free-falling health food packaging bag first contacts the guide plate, but also slows down the sliding speed of the health food packaging bag on the guide plate, thereby reducing the probability of the health food packaging bag rolling and shaking when it slides onto the belt, ensuring that the health food packaging bag can stay in the middle position of the belt, thereby avoiding weighing errors;

[0019] (2) The guide plate is divided into three sections, namely, a first guide plate and a second guide plate with decreasing width and inclination, and a third guide plate located between the first guide plate and the second guide plate to serve as a connecting transition. The limiting plates on both sides of the third guide plate have a guiding and limiting effect on the health food packaging bags passing through the third guide plate, so that the health food packaging bags dropped on different positions on the first guide plate can slide to the middle position of the belt;

[0020] (3) The flexible transition piece is arranged at one end of the second guide plate close to the belt. When the health food packaging bag passes by, multiple flexible rods contact and rub against the health food packaging bag at the same time, and convert part of the impact force of the health food packaging bag into energy for the flexible rods to generate vibration, further consuming the kinetic energy of the health food packaging bag. In addition, under the gravity of the health food packaging bag, the flexible transition piece will deform to a certain extent in the vertical direction, further reducing the height difference between the health food packaging bag and the belt, so that the health food packaging bag can stay stably in the middle position of the belt.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application.

[0028] Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present utility model.

[0029] As attached Figure 1-3 As shown, an online weighing auxiliary structure for health food packaging is arranged between a powder packaging machine 1 and a belt weighing scale 2.

[0030] The auxiliary structure includes a guide support assembly 3 , a blowing assembly 4 and a flexible transition piece 5 .

[0031] The guide support assembly 3 is installed and fixed below the discharge port 11 of the powder packaging machine 1 . Specifically, the guide support assembly 3 includes a first guide plate 31 , a second guide plate 32 , a third guide plate 33 and a limit plate 34 .

[0032] The first guide plate 31 and the second guide plate 32 are both rectangular plates. The length direction of the first guide plate 31, i.e., the Figure 1 The f direction is consistent with the downward direction of the health food packaging bag.

[0033] The inclination degree of the first guide plate 31 is greater than that of the second guide plate 32. In this embodiment, the angle between the first guide plate 31 and the horizontal direction is 45 degrees, and the angle between the second guide plate 32 and the horizontal direction is 30 degrees.

[0034] One end of the first guide plate 31 is fixedly connected to the discharge port 11 of the powder packaging machine 1 , and the other end of the first guide plate 31 is fixedly connected to the third guide plate 33 .

[0035] The width direction of the first guide plate 31, i.e. Figure 3 The width of the second guide plate 32 is smaller than that of the first guide plate 31, and the two ends of the third guide plate 33 are respectively connected to the first guide plate 31 and the second guide plate 32, so the third guide plate 33 is an isosceles trapezoidal plate structure for connecting the first guide plate 31 and the second guide plate 32. The angle between the third guide plate 33 and the horizontal direction is also 45 degrees.

[0036] The limiting plate 34 is a rectangular plate, and is vertically arranged at both ends of the first guide plate 31, the second guide plate 32 and the third guide plate 33 in the width direction. The height of the limiting plate 34 is greater than the thickness of the health food packaging bag to prevent the health food packaging bag from sliding off the guide plate.

[0037] The blowing assembly 4 includes a support rod 41, an air pipe 42 and an air nozzle 43. One end of the air pipe 42 is connected to the air source, and the other end is connected to the air nozzle 43. The support rod 41 is fixed to the powder packaging machine 1, and the support rod 41 is used to fix the air nozzle 43 and the air pipe 42 above the first guide plate 31.

[0038] When the health food packaging bag is falling freely, the trumpet-shaped air nozzle 43 can blow air toward the first guide plate 31 and the health food packaging bag on the first guide plate 31. The air volume and wind speed are determined according to the area and weight of the actual health food packaging bag, so as to reduce the sliding speed of the health food packaging bag on the first guide plate 31 and prevent the health food packaging bag from rolling and shaking after the free-falling health food packaging bag first contacts the first guide plate 31.

[0039] The angle between the blowing direction of the air nozzle 43 and the first guide plate 31 is in the range of 30-60 degrees. In the present embodiment, the angle between the blowing direction of the air nozzle 43 and the first guide plate 31 is preferably 45 degrees.

[0040] The second guide plate 32 extends obliquely downward to just above the belt 21 of the belt weighing scale 2 , and the flexible transition piece 5 is disposed at one end of the second guide plate 32 close to the belt 21 .

[0041] One end of the flexible transition piece 5 is fixed to the bottom of the second guide plate 32 , and the other end of the flexible transition piece 5 is suspended and arranged just above the middle position of the belt 21 .

[0042] As attached Figure 3 and attached Figure 4 As shown, the flexible transition piece 5 in this embodiment is composed of a number of long columnar flexible rods 51 arranged at equal intervals, and the flexible rods 51 are preferably made of silicone material in the prior art. The silicone material is elastic and not easy to break. When the health food packaging bag passes through the flexible transition piece 5, a plurality of flexible rods 51 contact and rub with the health food packaging bag at the same time, and convert part of the impact force of the health food packaging bag into energy for the flexible rods 51 to generate vibration, further consuming the kinetic energy of the health food packaging bag. In addition, under the action of the gravity of the health food packaging bag, the flexible transition piece 5 will deform to a certain extent in the vertical direction, thereby further reducing the height difference between the health food packaging bag and the belt 21, so that the health food packaging bag can stay stably in the middle position of the belt 21 after leaving the flexible transition piece 5.

[0043] The implementation principle of the above embodiment is:

[0044] When the health food packaging bag falls freely from the discharge port 11 of the powder packaging machine 1, the air blowing of the air nozzle 43 can prevent the health food packaging bag from rolling and shaking after contacting the first guide plate 31. Then the health food packaging bag slides down along the first guide plate 31, and the air nozzle 43 continues to blow air during this process to slow down the sliding speed of the health food packaging bag on the first guide plate 31. After passing through the third guide plate 33, the health food packaging bag is guided to the middle position in the width direction of the first guide plate 31. When the health food packaging bag slides down to the lowest end of the second guide plate 32, it contacts the flexible transition piece 5. After further absorbing and consuming the impact force and kinetic energy of the fall, the health food packaging bag falls steadily on the middle position of the belt 21 in the width direction perpendicular to the conveying direction, ensuring that the belt weighing scale 2 can accurately measure its weight, effectively avoiding the triggering of the rejection mechanism of the belt weighing scale 2 due to the error of the weighing result, thereby achieving the effect of reducing the unqualified rate and avoiding the waste of health food.

[0045] Although preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic creative concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
